Comment on the level-set method used in ‘Numerical study on mobilization of oil slugs in capillary model with level set approach’
(Peer reviewed; Journal article, 2016)This is a comment on a 2014 paper by Dai and Wang. It is argued that the validation in Dai and Wang's paper is an artifact caused by the boundary conditions of the level-set function, meaning that the effects reported in ... -
Numerical investigation of the effet of leakage flow through erosion-induced clearance gaps of guide vanes on the performance of Francis turbines
(Journal article; Peer reviewed, 2018)Abrasive wear in the clearance gap of guide vanes (GVs) increases the gap size, which deteriorates the flow and causes loss of efficiency. This paper investigates the performance of a Francis turbine including erosion-induced ... -
Optimization procedure for variable speed turbine design
(Journal article; Peer reviewed, 2018)This article outlines a design procedure for variable speed Francis turbines using optimization software. A fully parameterized turbine design procedure is implemented in MATLAB. ANSYS CFX is used to create hill diagrams ...
